Specication of Letters Patent.

Patented Nov. 6, 1906.

Application led July 16,1906. Serial No. 326.395.

`To all whom, it may concern.-

Be it known that I, WILLIAM D. LowRY, a

citizen of the United States, residing in the not necessarily, for use in passenger-cars.

`thereon.

It has for its object to produce a bod `bol ster which in the major is made o cast metal, preferably steel, and contemplates what I shall term a built-up structure, and by which construction-that is, forming the bolster as an entirety out of separate castings-I am enabled to handle the parts in the process of casting in a much more economical manner than if the bolster as an entirety were an integral casting.

A further object of this invention is to produce a separable bolster whereby the draftsills and their carried rigging can be easily removed therefrom for repairs, &c.

Figure I is a top or plan View of my imroved bod -bolster, aportion of some of the ongitudinalI sills being shown in position Fig. II is a front elevation of the same. Fig. III is a transverse section taken on the line III III, Fig. I. Fig. IV is a longitudinal section taken on line IV IV, Fig. I. Fig. Vis a longitudinal section taken on line V V, Fig. I. Fig. VI is a perspective view'of a portion of one member of the bolster employed in carrying out my invention.

1 1 indicate a pair of analogous parallel cast-metal members, each of which is provided with a recessed portion 2 in its under side and in which the draft-sills 3 3 of the draft-rigging are arranged.

4 indicates a centrally-arranged transverse connecting member, which, as is most clearly shown in Figs. I and IV, consists of a castmetal member deepest at its center, and at which point and upon its under face is the male member of a center bearing 4a. This connecting member is preferably of I-beam cross-section, the lower flanges of which are provided with suitable perforations for the passage of bolts. The upper flangesof I-beam-shaped member 'are also provided with perforations to receive bolts.

The ends of the connecting member 4 are designed to enter the .recesses 2 2 of each of the members 1, the lateral extensions 5 5 offering a compression-block for the said members 1 1, and also serve asa support for the draft-timbers arranged thereabove, said members 1 1 and the member 4 being secured together by bolts, as is clearly shown in the drawings.

The members 1 1 are preferably, like the member 4, I-beam-shaped in cross-section and the upper flanges of which are perforated at suitable distances a art to receive bolts which secure said mem ers 1 1 to the side, center, and intermediate sills of the carbody. The bolts, however, which secure the members 1 1 to the center sills also pass,

through the flanges of the draft-sills, as is clearly shown in Fig. II.

6 6 indicate tie-bars which are arranged parallel with the connecting member 4 and are secured to each member 1 1 near their ends by suitable rivets or bolts. These bars 6 6 also serve as side bearings for the truckbolster, as is well understood.

When it is desired to repair the draft-rigging, all that is necessary to do is to remove the nuts from the bolts which secure the connecting member 4 and the draft-sills 3 3 in place and lower said member and sills, after which they may be removed entirely from the car.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1 A car-bolster consisting'of a pair of par allel members each having a recessed under side with draft-sills located in the recessed portions, and a transversely-arranged connecting ember, fhrend of which transverse member enters the recessed under side of each parallel member respectively and form a com ression part therefor, substantially as set orth.

2. A car-bolster consisting of a pair of parallel members each having a recessed under side designed to receive draft-sills, and a- IOO the draft-timbers, substantill as set forth.

3. A. car-bolster consisting o a pair of parallel members each having a recessed under side,- draft-sills located in sad rec1esses and a transverse connecting mem er a so entering saiimed portions, and forming a compression part for each parallel member,which com ression parts also act as a support for the graft-timbers, substantially as set forth.

4. A body-b`o1ster consisting of two parallel cast-metal members, a centrallyflocated trylsxersely-arranged connecting member having a centeribearing, means-forseeuring said connecting -member to said" .paralle members,. and tie-bars connecting said parallel members near their ends, substantially as set forth.

5. .A body-bolster consisting of tWo parallel cast-metal members, a .centrally-located transversely-arranged .connecting member ha`v1`ga`center bearing, means for securin Said connectin member to said aralle members, and tle-bars connecting said) parallel members near their ends; said tie-bars also Aserving as side bearings, substantially as .setiforth WM. D. LOWRY.
